How these estimates are made

Aion 2

We estimate that about 820,000 people play Aion 2 on a typical day (most likely between 590,000 and 1,100,000), based on data from Nov 9, 2026. Around 1,200,000 accounts (between 910,000 and 1,500,000) have played it at some point. It is anchored on Steam’s official concurrent-player count, converted to daily players, so players on other launchers or consoles may not be fully counted. Confidence: medium — Steam covers part of the player base, or several community signals agree.
